Custom applications in C#/.NET, TypeScript/React, and Python - where off-the-shelf software ends. Web and mobile apps, backend APIs, B2B portals, and system integrations that replace spreadsheet processes and extend enterprise platforms. We work in your repositories, to your standards - delivering production-grade results, not prototypes.
Custom applications - from architecture through implementation to ongoing operations.
Production web applications with React 18, Next.js App Router, TypeScript, and TailwindCSS. Server components for SEO-critical pages, React Query for server state, Zustand for client state, and Playwright end-to-end coverage - deployed on Vercel or Azure Static Web Apps.
#React18 #Nextjs #TypeScript #TailwindCSS #ReactQuery #Zustand #Playwright
Scalable REST and GraphQL APIs with Node.js Fastify, .NET 8 Minimal APIs, or Spring Boot 3. OpenAPI contract-first design, JWT and OAuth 2.0 via Azure AD B2C, Prisma or Entity Framework Core for data access, and k6 load-tested before every release.
#NodejsFastify #DotNet8 #SpringBoot3 #OpenAPI #Prisma #EntityFramework #AzureADB2C
Cross-platform mobile apps for iOS and Android with React Native and Expo, or Flutter with Dart. Offline-first architecture using WatermelonDB, push notifications via Firebase Cloud Messaging, biometric authentication, and OTA updates with Expo EAS - no app store submission delay.

Business process applications that replace Excel-driven operations: approval workflows, operational cockpits, product configurators, and management reporting portals - built as governed, auditable web applications integrated to SAP, Salesforce, or Dynamics 365 via REST APIs and webhooks.
#WorkflowApps #ProcessAutomation #React #RESTAPIIntegration #SAP #Salesforce #Dynamics365
Architecture reviews, ADR authoring, and technology selection for greenfield builds and acquisition targets. Codebase quality assessed with SonarQube, dependency risk with OWASP Dependency-Check, and cloud cost modelling - delivering an actionable remediation roadmap with effort estimates per finding.

30% Efficiency GainWe chose ZirkelTech because we needed a strategic partner with world-class expertise to work alongside our multi-national SAP S/4 team. We found ZirkelTech to be the most flexible, well-organized and trustworthy. We highly appreciate not just the subject matter knowledge, but also the enthusiasm and readiness consistently shown by the colleagues to discuss and try out novel approaches to solving complex problems.
Our employees needed real-time assistance at all times. Equally important to us were feedback on work steps, intuitive usability, flexible application, and a solution that could be deployed at short notice. We achieved all of these goals with ZirkelTech and trust the new solution for digitizing our shopfloor processes.
ZirkelTech has supported us from the idea of a collaboration platform to its final marketability with high competence and reliability. Thanks to the partnership and agile cooperation, the idea was quickly transformed into a proof of concept.

ZirkelTech was instrumental in building our Personal Finance platform, MoolahMate. They delivered seamless integration with another solution provider, robust security, and stayed on time and on budget. Their ability to listen, suggest ideas, and their professionalism make them an invaluable partner. A pleasure to work with.
From the very first discovery workshop, the ZirkelTech team demonstrated a rare combination of deep technical knowledge and genuine curiosity about our manufacturing operations. Rather than proposing a generic off-the-shelf solution, they invested heavily in understanding our specific OEE (Overall Equipment Effectiveness) measurement methodology, our rejection-tracking workflows, and our compliance obligations under IATF 16949. This groundwork paid dividends throughout the entire project.
